摘　　要：本文介绍已建立的一套动态可见－红外图象转换系统，采用ＣｄＳ－ＣｄＳｅ光导薄膜型液晶光阀作为关键转换器件，实现了由可见图象到红外（８～１２μｍ）图象的视频转换，其对比度达∶１，响应时间为４０ｍｓ，极限分辨率为１０ｌｐ／ｍｍ．A Visible-to-infrared dynamic image converting system built for infrared simulation is described in this paper. It adoptS CdS-CdSe photoconductive thin-film type liquid crystal light valve (LCLV) as the key converting device. The video-rate conversion of visible image to infrared (8～12 μm) is realized. The contrast ratio of 9∶1, response time of 40 ms and limiting resolution of 101p/mm have been reached.
